I was reading the thread under Revolvers about the S&W with locks failing and locking up the action. I discovered that my Trooper MKIII will lock up under one circumstance. If you advance the cylinder about 1/8" at a time, by pulling the trigger a slight amount, releasing the trigger, repeating the process, that at a certain point in the rotation it locks up and you can no longer pull the trigger. You can then manually rotate the cylinder into index and everything is normal. I realize that this is an unusual way to index the cylinder, and under normal use (full pulls on the trigger double action) it never happens, but is this something I should have fixed? Thanks for any thoughts.
